> In this patch set we add skb_get_hash_perturb which gets the skbuff > hash for a packet and perturbs it using a provided key and jhash1. > This function is used in serveral qdiscs and eliminates many calls > to flow_dissector and jhash3 to get a perturbed hash for a packet. > > To handle the sch_choke issue (passes flow_keys in skbuff cb) we > add flow_keys_digest which is a digest of a flow constructed > from a flow_keys structure. > > This is the second version of these patches I posted a while ago, > and is prerequisite work to increasing the size of the flow_keys > structure and hashing over it (full IPv6 address, flow label, VLAN ID, > etc.). > > Version 2: > > - Add keyval parameter to __flow_hash_from_keys which allows caller to > set the initval for jhash > - Perturb always does flow dissection and creates hash based on > input perturb value which acts as the keyval to __flow_hash_from_keys > - Added a _flow_keys_digest_data which is used in make_flow_keys_digest. > This fills out the digest by populating individual fields instead > of copying the whole structure.
